Panel 2 Fig. 3 is a perspective of the fully formed caris demarked from'panel I by score line 29 which ton in its open position, showing its rectangular 35 extends clear across side flap 5 including marconstruction, and ready to receive sundry articles. ginal flap l6, while panel 1 is de'marked. from Fig. 4 is a bottom view thereof. 1 flap 8 by score line 36 which extendsclear across Fig. 5 is a side view of the container in closed side flap 5 including marginal flap l6. Diagonal and carrying position. j scoring lines are provided in the side flaps as Fig. 6 is a fragmentary longitudinal sectional O follows: 3|, extending from the juncture of score view of the closed container shown in Fig, 5.

Inbetween said panels I and |5-29 to 2|-36; 31, extending from the junc- 2 is a panel 3 destined to form the bottom of ture of score lines|5-29 to line 2|, and 38, ex-

destined in part tobe the side walls or panels The reinforcing portions l6, l3 and l8, l8, reof the container or carton. Continuous with said spectively, are folded along their respective score panels I and 2 respectively, are panels 6 and. l lines, viz: Portion I6 is. folded along line 28 and respectively, which are 1 destined to constitute 55 is secured to. the inner face of part 8 inany preferred manner. Reinforcing portion I3 is folded along scoring line 21, and secured to the inner face of part I I. The several tabs 3, l8, are folded along score lines I1, and secured to the inner faces of panels 4 and 5, respectively. Fig. 2 shows certain of the reinforcing portions before folding and securing, and certain others after this operation.

After the reinforcing operation, the upper part of the blank is bent at a'right angle along upper score line 25, while the side flap 4 is bent at a right angle to said upper part of the blank along score line 22. along score line [9 and placed beneath the bottom panel 3. Marginal flap i6 is bent at a right angle along score line I 5, so that when .the lower a panel is brought up it will oppose the inner surface thereof. Fig. 2 illustrates the position of the ,7 along scoring line 39 p is bent at a right angle a;

parts up to this point, with panel I and side'fiap 4 in vertical plane, and the remainderof the blank in horizontal plane. The operation iscontinued by bending'flap of side flap 5 at a right angle along score line I9, and bending panel 2 at a right angle along lower score line 25. Side flap 5 is then bentat a right 'anglealong score line 22. Flap 20 of sidegflap 5 is placed beneath bottom panel 3, and marginal flap I6 is bent at a right angle along score'line l5. Panel 2 will then parallel panel I and side flap 4 will parallel side flap 5 completing thecontainer. The marginal flaps are then glued, riveted or otherwisesecured to'panels l and ,2, respectively.

It will now be observed that medial score lines 2|, 2| of side flaps 4 and 5 are in a line or plane with score line 26 of the bottom panel 3. This fiat byinfolding along the said score lines. To facilitate this infolding at the bottom of the container, diagonal score lines 33, 34, 31 and 38 are provided. Fig. 7 shows clearly this latter flat feature.

Provision is also made for a similar infolding .35 enables the container to be accordioned jor'folded Fig. 5 shows the gabled top'form. This transtabs adapted to be'bent vently of the lower scored formation is accomplished by imposing pressure inwardly at the center of the triangular portions formed by the score lines 29, and 36 in the case of side flap 5 (Fig. 3), and score lines 23, 3|, and 32 in the case of side flap 4. Fig. 5 shows the result of this latter operation-namely, the boxlike or rectangular character of the carton is maintained with only the upper part infolded at the sides. This gabled effect and brings the handle pa'rts 8 H together. The tab and I4 is bent at a right angle and passed through the hand hole opening 9 in handle part 8. In the drawings, the carton has been shown as provided with snap fastener means40 applied to tab l4 and part 8 respectively. Other securing or locking means may be employed, or none, since frictional and fiexural upon to keep tab resistance alone may be relied M in engagement with part 8. a

Having described my invention, what I claim 1. A blank for folding into-"a lunch box and the like, comprising two main panels j0ined'by an intermediate panel-des'tinedto bethebottom of said box, a side flap extending laterallyfrom each of said main panels, said side" flaps havin at rightangles thereto and to be disposed against" andsecured'to said intermediate panel, marginal flaps on said side flaps adapted to be bent at rightanglesfand to be disposed in lapping relation toand to besecured to said main panels, .and vertically spacedapart upper and lower scored triangles on said side flaps to facilitate infolding 'of the. sideflflaps, said side flaps and bottom being scored medially and in a plane, when in boxe'dfup form, tof enable the latter to be collapsed by infoldingintofsubstantially flat form.
